I was curious what the "SC" slot above the HD on my E6420 was for is it some kind of expansion port? I cannot find referance of it function anywhere on the web site.
Isn't that the smart card slot??
Welcome to the Community. Bacillus is correct its the smard card slot, also called the express card slot. ( commonly wireless cards )
Hope this helps.
The SC slot and the ExpressCard slot are not the same. I have a Latitude E6410, and it has both a smart card (SC) slot on the left side and an ExpressCard (EC) slot on the right. The EC slot is about 3 times thicker. The smart card slot is for reading smart cards (http://en.wikipedia.org/wiki/Smart_card), and are a way to verify someone's identity to allow them to use the computer, and are common with the government and various companies. The Express Card (http://en.wikipedia.org/wiki/ExpressCard) slot is for expansion devices, like wireless cards or USB 3.0 ports. ExpressCard is the newer and much faster replacement standard to old PCMCIA cards.
